Cell phones have changed the way we live, and for any person a world without cellular telephone technology is not even imaginable. But all of the today’s advancement did not happen in merely a decade. Cell phones, like us have been developed over a long time.
Older telephones did not permit us to surf the Web or to go to online portal, watch films online, do online shopping and all. They even did not allow us to talk hassle readily. In this piece, we will take a look on the fascinating journey of cell phones, and how they became so smart. So here you go: Pre-standardization or ‘0G ‘ telephone services:
It can be said that it was a pre-standardization of cell phones, an age when cell phones were first built. AT&T was one of the first carriers to commercially exploit mobile phone in 1947. It was named as Mobile Telephone Service (MTS) for that time. It spread to more than hundred towns. Mobile phones had a half-duplex press-to-speak system where a user had to leave the button for listening and press for speaking. Telephones were also not compact. Later 1in 1965, the company introduced IMTS in The United States which grew to 40000 subscribers countrywide.
In 1960, world’s first totally automated mobile phone was introduced in Sweden. System allowed the use of a circular dialing knob for communication, which was fitted within a vehicle. It was named as MTA. In 1959, a company was born which is sometimes known as Motorola today, and Doctor. Martin Cooper, a researcher from the company, was the first individual to make a phone call from hand held mobile phone on April 3, 1973.
Analogue cellular networks or ‘1G’: It was the first generation of mobile networks and it is the model we use today. The 1st cellular network using multiple tower sites was developed in 1977 in Chicago. Developed by AT&T, it took 11 years to get FCC approval and more for going in the market. Another Asian firm NTT followed the trend and introduced similar network. It became the first of its kind to cover the entire country and modified its name to NMT in 1981. It spread extremely quickly in several other nations too , and was first to introduce world wandering.
Digital cellular network or ‘2G’: Later in 1990s, mobile devices became lighter and littler. GSM and CDMA standards were introduced in this age. SMS messaging happened, and first SMS got sent in 1992 in UK, thru a P. C.. After a year, first individual to person call was made in Finland using this network. Web surfing on mobile devices and downloading also were born in this age, and this technology is still in function.
Mobile broadband or ‘3G’: In 2001, NTT Docomo introduced 3G. Many nations followed the trend and soon it became widely adapted. Usage of this technology made things like Live TV and lightening fast online video streaming possible for mobile devices.
Native IP or ‘4G’: No official standard exist for 4G, still many handheld devices claim to support this technology and firms like LTE and Sprint also offer this technology. The major advancement is video streaming and Live Television, which is a lot quicker than 3G. Still because this standard is in a development phase, it does not even exist in some states like Australia.
Covering this engaging journey of cell phones in 700 words is not very easy. Still I have tried to cover each critical aspect of this revolution. I'm hoping you liked it. For many of users, this revolution is important, and for those who don't think that it is interesting, should switch to 2G networks and use them for watching YouTube videos. I suspect that can change their minds.
